.71 m l whom it may concern:

Be it known that I, SAMUEL LIrsoN, a citizen of the United States, residing at Saugus, in the county of Essex and State of Massachusetts, have invented an Improvement in Attachments for Garment-Cementing Machines, of which the following is a specification.

This invention relates to certain improvements in means for delivering cement to the work in a garment-cementing machine of the type shown in my prior Patent No.

6 l2,3 1 i, and more particularly to certain improvements in a cement-applying means used in connection therewith of the character shown in my Patent No. 1,039,681.

In the operation of machines of the character above referred to, it is necessary to apply cement to seams of varying widths, and it is obviously undesirable to apply cement over a greater surface than is necessary.

When using cement-applying devices such as have been previously disclosed by me, as above stated, great difliculty has been encountered in regulating the flow of the cement, so that it corresponded with the requirements of the work, this difficulty being partly due to the fact that these devices were so constructed that it was practically impossible for the operator to see that an ex cessive amount of cement was being delivered, until the cement flowed out beyond the sides of the cement-distributing means. Even if the amount of cement which was delivered in excess was small, these prior devices were likely to spread the cement over a considerably wider surface than was desirable. In practice it is necessary, or desirable, to spread the cement upon surfaces of different widths, and, after a seam has been formed, it is usually desired to cement a tape over the seam, so as to cover and strengthen it. For this reason the surfaces which are sometimes cemented are not per fectly flat, and, as the form of seams sometimes vary, it is desirable to adapt the cement-applying device to these different conditions.

The object of my invention is to provide a cementing-device of the above described character, which will only apply the cement to a surface of predetermined width, and which is constructed to permit the operator to observe the amount of cement which is Specification of Letters Patent.

being delivered to the Work, so that he may readily vary the extent of flow before such an excessive amount is delivered as to cause it to overflow at the sides of the cementdistributing means.

A further object is to produce a device of this character which will permit a quantity of cement which is considerably in excess of the required amount to be delivered without having it spread beyond the confines of the surface which is to be cemented.

A further object is to provide a device of this character with which the width of the surface cemented may be varied, and which is otherwise constructed to be adapted to varying conditions.

I accomplish these objects by the means shown in the accompanying drawings, in which Figure 1 is a side elevation, and Fig". 2 is a rear elevation of a cement-applying device made according to my invention. Fi 3 is a vertical central sectional view, taken on the line 3-3, of Fig. 2. Fig. 1 is a front elevation thereof. Fig. 5 is a sectional plan view on line 55, of 1. Fig. 6 is a side elevation of a modified form of my invention. Fig". 7 is a detail view of a part thereof. Fig. 8 is a detail sectional view of the foot employed in the form shown in Fig. 6. Figs. 9 and 10 are, respectively, side and front elevations of another modified form of my invention. Figs. 11 and 12 illustrate different forms of cement-distributinn plates.

In the drawing a indicates the usual cement tube which is connected to a suitable source of supply, said tube having deliv ery nozzle 5 at its lower end, which extends obliquely rearward, and is provided with a discharge opening 6 in its side, opening rearwardly.

A pair of Vertical guideways are formed in the sides of the discharge opening" 6 and a gatem is slidably mounted in said guideways, and is adapted, when moved to its lowest position, entirely to close said opening'. A controlling handle a is pivotally mounted on the tube a, and is connected by a link 0 to said slide, so that the latter may be readily raised and. lowered.

A collar 0 is slidably mounted on the tube a, and normally rests on a shoulder 6" formed on the head Z), and a spring d is interposed between said collar 0 and a fixed collar 6 on the tube, so that the sleeve 0 may be held by the action of said spring against the shoulder 5 The collar is encircled by a ring f of considerably greater internal diameter than the external diameter of the collar 0, and is pivotally connected to said collar by means of screws g, arranged at diametrically OPPOSlLQ sides thereof, permitting forward ind rearward tilting of said ring. A series of legs are integrally formed with said ring f, said legs being shown in Figs. 1 to 5, as four in number, and comprising a pair of front legs 72 and a pair of rear legs each leg having a roller is on its lower end, forming a carriage.

A pivot rod 79 is mounted in the rear legs a of the ring f, and a pair of right angularly shaped levers g are mounted in parallelism on said rod 39 at opposite sides of nozzle Z), said levers being substantially identical in form, and one arm of each lever being held in an a proximately horizontal position and the other depending from said rod p. The front ends of the horizontal arms are connected by three links q, the middle link being connected to the ring f by a coil spring 8, which tends to draw them upwardly.

Tae depending arms of the levers Q are each extended rearwardly at their lower ends, and are formed to provide cement-re taining plates 9 which extend upwardly to a point adjacent the upper end of the discharge opening I). The front edge of each depending arm extends obliquely rearward and is continuous with the lower edge of the plate portion 57?, which is a work-engaging edge, and is straight and normally held in a horizontal position. A pair of rolls 7c are respectively mounted on cars at the rear side of plates 9 each roll being arranged approximately tangentially to the horizontal plane of the work-engaging edge of the corresponding plate g and acting to press or hold the work onto the conveying or feeding table indicated by the line at.

Grooves are provided on the adjacent or inner sides of said plates g and a scraper, or cement-distributing plate 25 is mounted therein and forms, with said plates f, a cement conducting channel, the lower portion of which constitutes a cementretaining recess. The lower end of the plate 6 is held flush with the work-engaging edges of the plates 5/ and may be notched according to the shape of the seam over which the device is to be used, as illustrated in Figs. 11 and 12, or it may be straight. Said plates are clamped against the edges of the scraperplate a by means of right and left threaded screws a, a, in ears at the rear edges of the plates If it is desired to apply cement to surfaces of different widths, said levers 3 may be adjusted laterally toward or from nozzle 12 by means of said screws a, 24,

scraper plates 6 of the width and form desired being employed.

In operation, the cement will be delivered through the discharge orifice Z) against plate Z, or into the channel formed by the plates g and z. and will, therefore, flow down said channel onto the surface of the work and become distributed throughout the width of the plate 6, and will pass beneath the lower edge thereof so that a thin coating of cement will be applied to the work. The surplus cement will be retained in the recess formed by the middle plate 2' and side plates the latter preventing the cement from spreading laterally and causing the surface cemented to be of uniform width and equal to the space therebetween. As the space inclosed by said plates is open at the front, and the nozzle 5 held at a substantial distance above the lower ends of said plates 2, and 9 the operator may readily see if sufficient cement is he ing applied, and also, if the cement should flow so fast that it is likely to overflow at the front edges of the side plates 9 the flow may be reduced, the regulation being read ily accomplished by adjusting the con trolling-lever a. In this way the width of the surface cemented may be kept constant, but, if it is desired to increase or diminish the width of the surface cemented a scraperplate 2, of either greater or less width, corresponding to the width desired, will be insorted and the screws u, a, will be adjusted so as to clamp the scraper between the levers The lower edges of the scraper and plates are always held in close engagement with the work by the spring 3, and tilting of the carriage, which supports the distributing means on its pivots g, to conform to irregularities, is permitted without interfering with the operation of the levers g and parts carried thereby.

In Figs. 6 and 7 I show a somewhat modifled form of my invention, in which a presserfoot o is substituted for the two front rolls is on the legs 71,, said presser-foot being connected to a crossbar h extending between said legs. Said foot 1) comprises a U- shaped spring having a flat, work-engaging face on its under side, a friction ball 0 being held in a recess formed in the bearing portion of said foot, by means of a spring 21 The object of this foot is to press down the folds of the hem and also perform in part the same functions as the front rolls 70.

In Figs. 9 and 10 I show another modification, in which a ring f is slidably supported on tube a and is provided with rigid, depending arms f at each side, in the lower ends of which a pivot screw it is rotatably mounted, the opposite portions of said screw it being provided with right and left screw threads, and levers g", corresponding in all material respects to levers g, are threaded thereon, so that said screw a acts as a trunnion for pivotally supporting said levers and permits lateral adjustment thereof, as before described. A dovetail-shaped bar '10 is fitted in corresponding grooves formed in the front sides of the levers and a foot t corresponding to the foot o is mounted on the middle of said bar. The upper end of the foot is extended to engage a groove M in the middle of the screw a" to hold the foot in a middle position when the arms are laterally adjusted.

1. A cement applying device for cementing machines comprising a pair of levers pivoted at an intermediate point to swing about a common axis, a cement-retaining plate carried by each lever at its rear end, a distributing plate held between said retaining plates, a spring engaging the opposite ends of said levers and acting to hold the lewer edges of all of said plates against the work, and means for delivering cement to the space included by said plates, substantially as described.

2. A cement-applying device for cementing machines, comprising a delivery tube, a carriage pivotally connected thereto and having friction rolls for engaging the work, an arm pivotally mounted on said carriage, a cementdistributing plate carried by said arm, a spring engaging said arm to hold said plate against the work, and means for delivering the cement from said tube in front of said plate, substantially as described.

3. A cement-applying device for cementing machines, comprising a cement-delivering tube, a pair of arms pivotally connected to said tube, disposed at opposite sides there of and extending rearwardly therefrom, a cement-retaining plate at the rear end of each arm and a distributing plate held between said retaining plates and in the rear of said tube, substantially as described.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.
